[Bf-committers] new UV test grid

[Hubert Niećko]

Roger: pozdrowienia dla żony :)
to tell which way UV tex is oriented I prefer letters and numbers, as
I did in pic in BlenderArtist thread. If use arrows flipped UV faces
will not be so obvious. I didn't implemented it in python because
doing it per pixel is huge amount of work, and I think there are
easiest way to do text in C or even there is way to do this in python
but i don't know it. If there is I could try add this in python :)

Paolo: saturation slider should do exacly what you propose:
0=grayscale -> 0.5=color -> 1=more color :)
